Beit known that I, OSCAR HAMsrEmcf l'ersey City, in the county of VHudson, und Stute of' Nerv .forscht h'xi'vc invented a new and improved4 Electric'Appnrntus for Gas Engines; :ind I dnhereby declare that the fol,` lowing is n ihll,clear, and ejzsct'description thereof, which will enable those skilled in the nrt to make andusezwf the sume, referencebeing had to the *ccompnn'yingdrawing, forming part of this specification, in which#- v Figure 1 represents a 'plan or top View of this -inventonfpnrtly in section.

-The remnining ligur'es'are details and lmodiiicntions,which will be referred to as the description progresses; Similar lctterslof reference in these ifiews indicate' corresponding parts. Y y l This invention relates to sn electric apparatus, which is intended to he attached to or connected `with the I 'cylinder lol" n gas engine, ond wli'ichvis so arranged thnt,'by its action, the 4ciplosion of *the gas in said cylinder.

. isl eiiected at the proper intervals inn safe, sure, ondcconomical manner The invention consists in n ,pendulumswitch vwhichconnccts with one poleof n buttery, loud to which an Qscillntiug'motionis imparted by o reciprocating slide, or by nny'other .suitable means, in' such n manner that the sumo is alternately brought in contact with'two' stncls,.connectingzwith the mil'arners` at 'the opposite ends'oi'v4 the working cylinder, and 'that by this motion of the-pendulum`sivitch the gas in' said cylinder is exploded at the proper intervals. The intensity of the current is increased by on electromagnetic hammer, and bygrcomf 1 binntion helix or coil, which is applied in combination. with the battery, and the ribruting motion of said electro-L magnetic hammer is produced by serrctedbar or rack, attched to the slide'` or other part, which imparts motion when the sparks-are required, nn'd that all-waste of electricity and of v the materials required to produceuthe same is avoided. .l l represents s. bed-plate, which is msde'of cnst iron or .unycther suitable material, and which is intended to he attached to the working cylinder o f 'u gnsengine,lor which maybe secured in any convenient spt close I 'Y tothe pendulumswitchin such a manner that s. powerful spark is obtained with o, comparatively wealc battery and with a small expenditure of acid, the whole apparatusbeing so arranged that it operates just at the time to or in the neighborhood, of said cylinder. I One end of 'this bed-plate s ervcsto support the buttery. B, {vhich constructedlis follows: The positive pole-plates P nre nnde of circular grates, cost of zinc, as shown in Figure` land f or' thc negative poles N I use one or two series of s 'nirnls of fine silverV wire, or copper wirelpla'ted with' silver or platina.. according to Smees principle, nndlconnected'together by stoutarms of copper, us shown par'- ticllarly in Figure 4. Said arms radiate from the inner ends ofcylinders a of copper or other metal, which nre in metallic contact witlrrailsb 6*, as will be presently uiorefully explained. Through the cylinders a, und insulated from the some by-dislrs c f gutta. perche, or otherpliitahlematerial, pass the tubes or rods d, which sup- .l port the positivel pole-plotse P, und which' are in' metallic contact with the rails b b*. The rails btand b b* are lecuredto n cross, he, which is'mede ofwoo'd o rother .noncnduot'or of electricity, and from which the positive and negative plates P and are suspended. The rnils b and are in metallic lcontact with the oentrnl stud f, to which is also attached a handle, for the purpose of raising the plltesont of the ncidgend by these 'means the positive pole of dne cup' connectswith the negative pole of the other cup. l The rails 6* andbl* are in metallic contact withstnds g g', which, when thecpparatu's'is in operation, rest upon metal columns h fr', lend the lower ends of"1'rhi cl1 1- msy be formed in to points, so that they irill drop into corresponding cvitiesjin the top ends of the columns', and thereby the cross with the pole-plates, willA be preventedfrom being displaced accidentally. whenV the battery is not used, the cross is raised and a stop, of wood or any other suitable material is put under the scuie,so that the zinc-.'plstesare lifted out'of the acid and the action'of the'batteryceases. The

columns kk connect euch with one of the ends 10 and 11 of the main` wireof the coil'or-"hclix C. This helix is. enclosed in n box, D, and it consists of 'two or more hollow gloss rollers )'on which is wounds ne iuduction "i wire of copper.,` This rinductionwire is covered by glass tuhes .k, which are secured in place by'means of beeswax and rosin. On the outer ends ofthe vglass rollersf'jW-sre mounted disks Z of `well-vanished wood or other suitable insulating material, which sre perforated with lilegthrough which the ends of thewires pass, as shown 'in lig. 1 oftliedrowing, and their inner ends are presided-limb flanges l', slsope'rforsted' with holes, through which the wires pass. This main wire is wound on the glass tubes k, and it is covered by au insulated layer of varnished paper or other suitable material, on which 4is wound a fine iron wie,well varnsheil, and covered with silkor wool; or, instead of using fine covered iron wire, thick uncovered iron wire, well coated with varnish, can

he used. This wire is wound so'that all clichy-ers run in one and the saine direction, and it serves to' increase the power of the induction the samcas u. bunch of metal rods introduced into thel interior 'ci' the holler!Y glass rollers j. After the wire is properly wound, and the bunch of metal rods adjusted in position, the intervening flanges Z are well covered with melted wax or rosin, and` firmly pressed together, and thereby the whole coil is united, andV the transit of the spark from 'one to the other of thewires passing out through the'holes in said flanges is prevented". f

Tneiends of the wires are combined, riz; those ct the induction-wirey of copper, and also those of the line covered iron wire, when such is used, and onc end of the con'ibined induction-wires is'brought in'v metallic con# tact with the pcnduluiu-sii'itcli G, and the other end with theengine, or if covered iron wire is used, the's'econd end of the combined induction-wires is connected with one end of said ii'onwiro, the'other endof which connects 'with 'the engine. The ends12-and`13 of the main wire, passing 'out between the intervening flanges Z, are in metallic contact, one `with the electric hammer E, and the other with the anvil 1'", (sealig. 3,) The electric hammer` E is secured to oneor'two spring-arms m, which retain the same in such a. position that'its lower face 'stands a little' :there the surface ofthe ani'il,.."aud itsuppor-face.little below th'epoint ota set-soreujp, whicl.i

screws into .a standard-,"o, and which can 'be adjustcdvso as 'tob'ringvits point to'thc'desircil distancefrom the upper face 'of' the haninier. The faces of thc haulnie'r, and also that oi"v thcanvil, are covered with flishssa platina, whereby thc electric action thereof ismaterially improved. From the electric hammer rises a pointer:

triangular s addlc,21, and 'fi sc rratedbaror.rack, q, which is attached to"a.'i'ecipr ocating slide, H, sweeps over this saddle, and imparts tothe hammer a rapid vibrating-motion','wherebythe faces'oithe-'same are alternately brought iu contact 'with vthe anvil and with the point of the 'setfscrew ju, and the'req'uired interruptions ofthe v current are effected. Fi-om the top of. .the slide rises a standard, r, and as sitid ,slide reciprocates,fthe f`e of." this standard hears againstasprins,which `is connected tothe penduluinLswitchG.
